No, it is browned. Browning and blueing are two different processes. Similar but they use different chemicals. Some parts were blued and some parts were browned. That receiver has been re-browned.

Check ordnance memoranda 22 for the processes. Rock Island's annual report, 1891 if I recall, also has a detailed report on both.
